A wide dynamic range image sensor provides individual pixel reset to vary the integration time of individual pixels. The integration time of each pixel is controlled by column and row reset control signals which activate a logical reset transistor only when both signals coincide for a given pixel.

Eric R Fossum, Gregory Waligorski: Pulse-controlled light emitting diode source. Photobit Corporation, Fish & Richardson P C, April 24, 2001: US06222172 (64 worldwide citation)

A light-emitting diode array is driven by a digital control. The digital control modulates the pulse width of pulses applied to the light-emitting diode. The intensity of the output is controlled by controlling the width of pulses applied to the light-emitting diode. Since light-emitting diodes have ...

Vladimir Berezin, Eric R Fossum: Active pixel sensor with fully-depleted buried photoreceptor. Photobit Corporation, Fish & Richardson P C, May 14, 2002: US06388243 (57 worldwide citation)

A fully depleted photodiode accumulates charge into both the diode and a separate floating diffusion. The floating diffusion has less capacitance that the overall diode, thereby resulting in a knee-shaped transfer characteristic for charge accumulation. The fully depleted photodiode also include two ...
